Question

If the area of a rectangle is 98x2, find the length and breadth of the rectangle and hence find its perimeter​

Answer 1

Answer:Length=98m

Breadth=2m

Perimeter=200m

Step-by-step explanation:

Area of rectangle=LengthxBreadth

=LengthxBreadth=98x2

=Length is 98m and Breadth is 2 m.

Perimeter of rectangle=2(l+b)

=2(98+2)

=200.

Answer 2

Answer:

Step-by-step explanation:

It is given that

Area of a rectangular field 25x

2

+20xy+3y

2

square unit

Length =5x+3y unit

We know that

Breadth = Area / Legth

So we get

=(25x+20xy+3y

2

)/(5x+3y)

=5x+y units

Now the perimeter of the rectangular field = 2 (length + breadth)

Substitute the values

=295x+3y+5x+y)

So we get

=2(10x+4y)

=20x+8y
